Which doesn't really prove anything (you believe website polls are scientifically accurate?). For all we know those could be cases of faulty hardware, subjective mis-impressions on their parts as to the contrast changing, or people just making up responses to the poll.
I have never heard of any technical information that says eInk screens have a finite lifespan with regards to fading/contrast. If you know otherwise, please provide links.
